A. Okwu mmalite na HPMC:
1. Ngwakọta kemịkalụ na nhazi:
Hydroxypropyl Methylcellulose (HPMC) bụ ọkara sịntetik, polymer soluble mmiri nke ewepụtara na cellulose.
Ọdịdị molekụla ya nwere agbụ azụ azụ cellulose nwere hydroxypropyl na methyl substituents.
Mgbanwe a na-eme ka ọ dị nro, nkwụsi ike, na ịrụ ọrụ na ngwa dị iche iche.
2. Njirimara nke HPMC:
HPMC na-egosipụta akụrụngwa dị ka ịgba, imepụta ihe nkiri, njide, nkwụsi ike, na njide mmiri.
Ọ na-etolite ihe ngwọta na-enweghị atụ, nke na-enweghị ụcha na nnukwu viscosity, na-enye aka na ọdịdị a chọrọ na ọdịdị na mmiri mmiri na-asa efere.
Ike imepụta ihe nkiri HPMC na-enyere aka ịmepụta oyi akwa na-echebe n'elu, na-enyere aka na mwepụ griiz na nchebe efere.
B. Ọrụ nke HPMC na mmiri mmiri ịsa efere:
1. Ịba ụba na njikwa viscosity:
HPMC na-eje ozi dị ka ihe na-emekọ ihe, na-eme ka viscosity nke mmiri na-asa efere.
Viscosity a na-achịkwa na-eme ka a na-agbasasịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsịsị akwụkwọ) na-eme ka ihe ndị na-arụ ọrụ na-agbasa, na-eme ka nrụpụta ngwaahịa na ahụmịhe onye ọrụ dịkwuo mma.
2. Nkwụsị na Nkwụsi ike:
Na mmiri mmiri na-asa efere, HPMC na-enyere aka kwụsịtụ irighiri ihe ndị na-adịghị soluble, na-egbochi idozi na ịhụ na otu ngwaahịa.
Ọ na-eme ka usoro ahụ guzosie ike megide nkewa nke ngalaba ma na-edobe nkwekọ ngwaahịa n'ime oge.
3. Nhazi ihe nkiri na arụ ọrụ nhicha:
HPMC na-enye aka n'ichebe ihe nkiri dị mkpa n'elu efere efere, na-enyere aka na mwepụ nke ala na igbochi redeposition nke irighiri nri.
Ihe nkiri a na-akwalitekwa ihe mkpuchi mmiri, na-akwalite ihicha ngwa ngwa na nsonaazụ enweghị ntụpọ.
Usoro mmepụta nke HPMC:
1. Nnweta akụrụngwa:
Mmepụta HPMC na-amalitekarị site n'iwepụta cellulose sitere na osisi pulp ma ọ bụ eriri owu.
Cellulose na-enweta ọgwụgwọ kemịkalụ iwebata hydroxypropyl na otu methyl, na-enye HPMC.
2. Mgbanwe na Ọcha:
Mmeghachi omume kemịkalụ achịkwara n'okpuru ọnọdụ ụfọdụ na-eduga na mgbanwe nke cellulose n'ime HPMC.
Usoro dị ọcha na-ahụ na mwepụ nke adịghị ọcha na nhazi nke ịdị arọ molekụla HPMC na viscosity.
3. Ngwakọta nhazi:
Ndị na-emepụta ihe na-etinye HPMC n'ụdị mmiri mmiri ịsa efere n'oge oge ngwakọta.
Kpọmkwem akara nke HPMC ịta na urughuru size nkesa dị oké mkpa maka ọbọ chọrọ ngwaahịa arụmọrụ.
D. Mmetụta Gburugburu Ebe obibi na Nleba anya n'ịdịgide:
1. Mmebi ndụ:
A na-ahụta HPMC dị ka ihe na-emebi emebi n'okpuru ọnọdụ dabara adaba, na-agbada n'ime ngwaahịa na-adịghị emerụ ahụ ka oge na-aga.
Otú ọ dị, ọnụ ọgụgụ nke biodegradation nwere ike ịdịgasị iche dabere n'ihe gbasara gburugburu ebe obibi na nhazi nhazi.
2. Ijikwa Isi mmalite emeghari ohuru:
Cellulose, ihe bụ isi akụrụngwa maka HPMC, sitere na isi mmalite dị ka osisi na owu.
Omume ọhịa na-adịgide adịgide na ị nweta ọrụ dị mkpa na-enye aka na nzere gburugburu ebe obibi nke HPMC.
3. Mkpofu na njikwa mkpofu:
Ụzọ mkpofu kwesịrị ekwesị, gụnyere imegharị ihe na composting, nwere ike ibelata mmetụta gburugburu ebe obibi nke ngwaahịa nwere HPMC.
Ụlọ ọrụ ọgwụgwọ mmiri na-adịghị mma nke ọma nwere ike wepụ ihe fọdụrụ HPMC na nsị, na-ebelata ihe egwu gburugburu ebe obibi Atụmatụ Ahụike na Nchekwa:
1. Nrube isi n'usoro iwu:
HPMC a na-eji mmiri mmiri na-asa efere ga-agbasorịrị ụkpụrụ iwu nke ndị ọchịchị setịpụrụ dị ka FDA (Nchịkwa nri na ọgwụ ọjọọ) na EPA (Environmental Protection Agency).
Usoro njikwa mma siri ike na-ahụ maka nchekwa ngwaahịa yana nrube isi na oke ekwenyere maka adịghị ọcha.
2. Mmetụta akpụkpọ na mgbakasị ahụ:
Ọ bụ ezie na a na-ahụta HPMC ka ọ dị mma maka iji ya na ngwaahịa ụlọ, ndị nwere akpụkpọ ahụ nwere ike ịnwe obere mgbakasị ahụ.
Omume ejizi nke ọma na iji ngwa nchedo onwe onye (PPE) n'oge nrụpụta na-ebelata ihe egwu nwere ike ime.
3. Ihe ize ndụ ikuku ume na mkpughe:
Ekwesịrị ibelata ikuku ume nke uzuzu HPMC ma ọ bụ ikuku ikuku iji gbochie mgbakasị iku ume.
Igwe ikuku zuru oke na njikwa injinia na ụlọ nrụpụta na-enyere aka belata ihe egwu mkpughe maka ndị ọrụ.
HPMC na-arụ ọrụ dị iche iche na nhazi mmiri ịsa efere, na-enye aka na njikwa viscosity, nkwụsi ike, ịrụ ọrụ nhicha, yana ndakọrịta gburugburu ebe obibi. Ngwongwo ya dị iche iche, yana usoro ị nweta nri na-adigide yana nrube isi nke usoro, na-egosi mkpa ọ dị na ngwaahịa nhicha ụlọ ọgbara ọhụrụ. Ka ndị na-azụ ahịa na-ebutewanye nrụpụta ọrụ, nchekwa, na nkwado, ọrụ HPMC na ịsa mmiri dị njikere ịmalite, na-ebugharị ihe ọhụrụ na nkwalite na-aga n'ihu na nhazi ngwaahịa.
